How are you going to get the old oil out? I understand there is no drain plug and has to be 'vacuumed' out?

Alex Bel

Is it true? I have no idea then. What other people do?

Bob338

I've read that some place. It was never an issue for me. While I have several Benz' and do mechanical and other work on them, I refuse to mess with oil in engines, tranny's or differentials. Don't want the mess from possible spills in my garages, nor the problems with properly disposing of the used material. I pay others to do all that and will do so on future oil changes.

Regardless, I've found great review on Amazon link for "Mityvac 7201 Fluid Evacuator Plus"

The topic is below and the author describes oil change on his 2007 Mercedes E320 Diesel (and other his cars): http://www.amazon.com/review/R2TCXV3...ore=automotive

I have had one of those for years. Works well. Use it on all my cars, boats, lawn mowers, snowblowers for extracting oil.

Dealers also use vacuum extractor for all MB cars.

No mess, except you need to be careful to put filter into plastic bag or container immediately you pull it out. Be careful to insert seals properly when replacing filters.

I have used a fluid evacuator on my TDI before. The version I have uses the dipstick hole. After using the evacuator, I unplugged the drain plug and it still drained 1/2 a litter of oil. It really depends on the model of car you are working on. The object is to get the hose to the bottom to be able to extract all the oil. I am not sure if the GLK even has a dipstick. My BMW does not have one.

There is a drain plug for the oil pan. If you use the drain method, you should also purchase a new washer for the plug and replace with each oil change. You will have to remove the belly pan to get access to the oil plug.

Call me old fashioned, but I just like draining the oil out the bottom vs. the vacuum method.

Wow! No wonder its a $300 oil change at the dealer!

Ok, I'm curious about actual experience on how folks did their oil/filter change on the 250 BT.

I'm at 1300 miles on my 2014 250 BT and the oil looks seriously dirty. That dirt definitely has me ready to do an oil/filter change very soon and make sure that all the old oil comes out.

Cheers,
Mike

Mike,

You are right. The oil gets black very quickly, but that is common to the industrial diesels that I've worked around in the past. Since the fuel has a higher oil content, the crankcase oil turns dark much quicker than a gasoline engine. I'm at 8700 miles and plan to change the oil/filter at 10K. My last two vehicles (gasoline engines) had change intervals at 7500 miles, so 10k is not that much farther. Please note that I'll accumulate 10K miles in less than 6 months, so there's no chance I'll hit the one year mark to require a change based on time.

I decided to let the factory oil run the recommended mileage, but I might change more frequently for the subsequent oil. Still undecided right now.

You really cannot do any damage to your engine to change more frequently, just your wallet. But the dark oil is not a reason for concern, especially for a diesel. FYI, I haven't added a drop of oil, yet.

Bob338

Has to be your first diesel! The carbon in the fuel colors the oil just like it was a paint dye. Don't worry about it.

First Benz diesel I had over 35 years ago I started changing the oil expecting it to clean up after the first time or two. Even flushed it after the first change when the oil turned black in less that a thousand miles. Thought something was seriously wrong. Must have run a case of oil through that thing and spent a lot of money and effort, until somebody clued me in. Now I don't even look at it. You'll never find a diesel with clean, clear oil! Do what makes you happy but don't expect 'clean' oil!

MikeDuncan

Thanks for the feedback about the oil, Mike and Bob. Yep, this is my first diesel. Any other nice to know tidbits? I know in the old days that checking the fuel filter bowl for water and draining them was important, but I haven't seen any mention of fuel filters in the owners manual.

Cheers,
Mike

Fuel filter is located on top, under the hood. Change interval is 40k miles.
